Step-by-step explanation:
The stratified sampling works as follows:
stratified sampling = (Population of subgroups)*(total sample size)/(entire population)
in this case, sample size = 80
entire population = 140 + 150 + 150 + 180 + 180 = 800
Population sample is the number of students of each year (for year 7, the population of subgroup is 140, and so on)
whith this equation we can find all the missing values:
a = (140)*(80/800) = 14
b = (150)*(80/800) = 15
c = (150)*(80/800) = 15
d = (180)*(80/800) = 18
e = (180)*(80/800) = 18

O 44 x 4-7
Answer:
D. 4^4 x 4^-7
Step-by-step explanation:
Option D is correct, 4⁴×4⁻⁷ is equivalent to the expression 1/64
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 1/64
One divided by sixty four
We need to find the expression which is equivalent to One divided by sixty four.
We know that 4×4×4 is 64
Which means 4³=64
4⁴×4⁻⁷ = 4⁻³
1/64 = 1/4³
= 4⁻³
So 4⁴×4⁻⁷ is equal to 1/64
Hence, Option D is correct, 4⁴×4⁻⁷ is equivalent to the expression 1/64

The expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the amount of money saved by Erica is $40. The expression which represents the savings will be,
40 + 40 = 80
40 x 2 = 80
Therefore, the expression which shows the saving is 40 + 40 and 40 x 2. The correct options are C and D.

Simplify: 4(36)?????
Answer:
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF). So, 436 = 4÷436÷4 = 19. Thus, 436 is equivalent to 19 in the reduced form.
Step-by-step explanation:
The solution for the expression 4(36) after you simplify can be expressed as 144.
What is 4(36) when you simplify?To simplify the expression 4(36), we need to perform the multiplication operation.
4 multiplied by 36 can be calculated as follows:
4 x 6 = 24 (multiplying the units digit)
4 x 30 = 120 (multiplying the tens digit)
Now, we add the results together:
24 + 120 = 144
Therefore, the number 4 multiplied by the number 36in brackets is equals to 144.

Given slope= 1/2 and a point (0,8), Write the equation of the line in standard form (PLEASE ITS DUE IN A LITTLE AND I NEED HELP PRONTO)
Answer:

Step-by-step explanation:
The slope is 0.5 so y=0.5x. We can plug in the point to the equation and we get 8=0(0.5)+b or 8=0+b. b=8 so the equation is y=0.5x+8
36 students signed up to volunteer for a race two or three equal groups of students and each group had a different task how many students were in each group
Answer:
I two groups are formed: 18 students
If 3 groups are formed: 12 students
Step-by-step explanation:
We will answer this problem based on two occurrences:
1. The students chose to form only two groups:
If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.
2. The students chose to form three groups:
If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.

k=2
k = 2/3
k = 3/2
k= 3
Answer:
The constant of proportionality is k = [tex]\frac{2}{3}[/tex] ⇒ B
Step-by-step explanation:
The form of the equation of the proportionality is y = k x, where
k is the constant of proportionality∵ Marjorie made 4 wreaths in 6 hours
→ Let y the number of wreath and x is the time of making them
∵ y = k x
∵ y = 4 and x = 6
→ Substitute them in the equation
∴ 4 = k(6)
∴ 4 = 6k
→ Divide both sides by 6 to find k
∵ [tex]\frac{4}{6}[/tex] = [tex]\frac{6k}{6}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
Let us use the other information to be sure it will give us the same value of k
∵ She made 6 wreaths in 9 hours
∴ y = 6 and x = 9
→ Substitute them in the equation
∵ 6 = k(9)
∴ 6 = 9k
→ Divide both sides by 9 to find k
∵ [tex]\frac{6}{9}[/tex] = [tex]\frac{9k}{9}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
∴ The constant of proportionality is k = [tex]\frac{2}{3}[/tex]
